17、or the conservation of the initial characteristics of cloth subjected to repeated laundering, is under consider- ation. In the first case, some tests may be carried out on the articles themselves, which may be re-used. However, for measurement of greying and yellowing, it is essential to use unsoile

18、d control cloths. Furthermore, as the measurement of certain characteristics of the household textile articles, particularly their mechanical properties, entails the destruction of samples, it is quite impossible to Perform these tests on household textile articles which are in use. lt has therefore

19、 been proposed to define the harmlessness of a laundering process on household textile articles by reference to the behaviour of control material treated in the same way at the same time as the cloth washed in the normal manner. Since the behaviour of household textile articles in use is in- fluence

20、d by many and complex factors, and depends to a large extent on the yarn linear density of the cloth, it is necessary, in Order to obtain satisfactory reproducibility of the results, to standardize all matters relating to the preparation of the control cloth, and to its use. In this International St

21、andard, the characteristics of the control cloth are defined with the greatest possible precision, and its use is standardized. The test methods to be applied to the control cloth before and after use are described in ISO 4312. 1 Scope and field of application This International Standard specifies t

22、he characteristics of a cotton material and the preliminary treatments which are to be applied to it in Order to make it an unsoiTed cotton control clothl) for the testing of certain effects of laundering. lt also defines the conditions of use of this control cloth (in the form of control test piece

23、s) during the laundering processes which are being tested from the Point of view of the conserv- s ation of the original characteristics of the cloth. The unsoiled cotton control cloth is primarily intended to enable the laundering of white cloth to be tested. lt may be used with all detergents and

24、all types of domestic or industrial machines designed to wash, hydroextract and dry household textile articles. The unsoiled cotton control cloth may also be used for testing the laundering of other categories of textile articles (coloured, for example). 2 References ISO 2, Textiles - Designation of

NOTE - The qualitative and quantitative variability of soiling in household textile articles which have been washed in the normal way, depending on the circumstance

As a result, the conclusions arrived at from the ap- plication of this International Standard will depend, to some extent, on what constitutes normally soiled articles in the p

They are usually of the Order of 3 to 8 % in the warp and 1 to 5 % in the weft for stabilized cloth “direct from the loom”. If it is necessary, for certain tests, to use soiled artic
